Pierre Robin sequence (PRS) is classically described as a triad of micrognathia, glossoptosis, and airway obstruction. Infants frequently present at birth with a hypoplastic mandible and difficulty breathing. The smaller mandible displaces the tongue posteriorly, resulting in obstruction of the airway. ⋯ A proportion of PRS infants do not respond to conservative measures and will require further intervention. Prior to considering any surgical procedure, the clinician should first rule out any sources of obstruction below the base of the tongue that would necessitate a tracheostomy. The two most common procedures for treatment, tongue-lip adhesion and distraction osteogenesis of the mandible, are discussed.

Although most cases of craniosynostosis are nonsyndromic, craniosynostosis is known to occur in conjunction with other anomalies in well-defined patterns that make up clinically recognized syndromes. Patients with syndromic craniosynostoses are much more complicated to care for, requiring a multidisciplinary approach to address all of their needs effectively. ⋯ General principles including skull development, the risk of developing increased intracranial pressure in craniosynostosis syndromes, and techniques to measure intracranial pressure are discussed. Evolving techniques of the established operative management of craniosynostosis are discussed together with more recent techniques including spring cranioplasty and posterior cranial vault distraction osteogenesis.
